Looking to get some I was wondering where is the best place to buy from? Has anyone bought the ones from troyer, if so how are they?

 

i've got troyer pully's. didnt get them directly from him but from a member here on f150online. They seemed to have given the truck more pep. The one thing i did notice immediately was the lower idle when at a red light but other than that, all i can say is that combined with the right exhaust, computer tune and intake, the pully's seem to help compliment the whole thing well. certainly worth the money if your looking for something to give the truck a little more pep. good luck with whatever you decide

 

X2....I got the UDP crank pulley for my v6 from Troyers and yeah the revs are lower at idle but there is a noticable increase in acceleration, combined with the AF1 intake I'm getting way better mileage.
